Version of EPW used in Nano Letters, 20, 8861 (2020)

[Vahid]

Dear EPW community,

The above paper by Dr. Poncé and Prof. Giustino in Nano Letters, 2020, uses a pre release version of EPW. Has this version been released? They use only one k/q point along the vacuum. Could their results be obtained by the latest version of EPW?

Any clarification on this question is greatly appreciated.

Dear Vahid,

The version has been released in QE 6.8 and include Hall factor.

Note that 2D with only 1 k/q point along the vacuum is possible in this case because it is graphene (a non polar material) and therefore no specific 2D electrostatic is needed for the Frohlich part.
For 2D polar materials, you can use the (not officially supported) system_2d input variable.

We hope to support 2D polar material for the next release.

Best wishes,
Samuel.
